Putting Extra on Car Payment Calculator

Reviewed by Calculator Editorial Team

Paying extra on your car loan can significantly reduce your interest costs and pay off your loan faster. This calculator helps you determine exactly how much you'll save by making additional payments and how quickly you'll be debt-free.

How Putting Extra on Car Payments Works

When you make additional payments on your car loan, you're essentially paying down the principal balance faster. This reduces the amount of interest you'll pay over the life of the loan. Here's how it works:

How Extra Payments Affect Your Loan

Each extra payment you make goes directly toward reducing the principal balance of your loan. Because interest is calculated on the remaining balance, paying down the principal faster means you'll pay less in interest over time.

Formula for Extra Payments

When you make an extra payment, the new principal balance is calculated as:

New Principal = Original Principal - Extra Payment

Then, the next month's payment is calculated based on this new principal balance.

Interest Savings

The key benefit of making extra payments is the interest savings. Each additional payment you make reduces the total interest you'll pay on the loan. The more you pay extra, the more you'll save in interest costs.

Example: Extra $200 Payment

If you have a $20,000 car loan at 5% APR, making an extra $200 payment each month will:

  • Reduce your principal by $200 each month
  • Save you approximately $1,200 in interest over one year
  • Pay off your loan about 18 months earlier than if you made no extra payments

How to Use the Calculator

Our car payment calculator makes it easy to see the impact of making extra payments on your loan. Here's how to use it:

  1. Enter your current loan balance in the "Loan Balance" field
  2. Enter your current monthly payment in the "Monthly Payment" field
  3. Enter your interest rate in the "Interest Rate" field
  4. Enter the amount of your extra payment in the "Extra Payment" field
  5. Click the "Calculate" button to see your results

The calculator will show you:

  • How much you'll save in interest
  • How much faster you'll pay off your loan
  • A breakdown of your payment schedule with extra payments

Tip: The calculator assumes you'll make the same extra payment each month. If you plan to make irregular extra payments, you may need to adjust your results accordingly.

Examples of Extra Payments

Here are some examples of how making extra payments can affect your car loan:

Loan Balance Interest Rate Extra Payment Interest Saved Months Saved
$20,000 5% $200 $1,200 18
$30,000 4.5% $300 $1,800 24
$15,000 6% $150 $900 12

These examples show how making regular extra payments can significantly reduce your interest costs and pay off your loan faster. The actual savings will vary based on your specific loan terms and payment history.

Frequently Asked Questions

How much can I save by making extra payments on my car loan?

The amount you can save depends on your loan balance, interest rate, and how much you pay extra each month. Generally, the more you pay extra, the more you'll save in interest and pay off your loan faster. Our calculator shows you the exact savings for your specific situation.

Is it better to make extra payments at the beginning or end of the loan term?

Making extra payments at the beginning of your loan term is generally more beneficial because you'll be paying down the principal when the interest rate is highest. This means you'll save more in interest costs and pay off your loan faster than if you made the same extra payments at the end of the loan term.

Can I make extra payments without penalty?

Most lenders allow you to make extra payments on your car loan without penalty. However, it's always a good idea to check with your lender to confirm their policy. Some lenders may have specific requirements for making extra payments, such as minimum amounts or timing restrictions.

How often should I make extra payments?

You can make extra payments as often as you want, but making them regularly (such as monthly) will give you the most consistent savings. If you can only make occasional extra payments, focus on making them when your loan balance is highest to maximize your interest savings.
